iCEdragon Demo Board Default Jumper SettingsTable 1. iCEdragon Demo Board Default Jumper Settings
Qualcomm IR-I2C Bridge Demo SetupThe iCE40 FPGA on the iCEdragon Demo Board comes pre-programmed with the Qualcomm IR-I2C Bridge Demo described below. The programming file and source code for this demo can be downloaded from the Lattice website at www.latticesemi.com/boards (navigate to the iCEdragon Demo Board page).
The Qualcomm IR-I2C Bridge Demo setup consists of the iCEdragon Demo Board which includes an IR-Receiver interfaced with an iCE40 ultra-low density FPGA. The iCEdragon Demo Board is interfaced with a J6 connector (Sensor board) of the DragonBoard using I2C and interrupt lines. A Sony RMTD301 is used as the IR-Transmitter.
RS232 and OTG-to-USB connections are made between the DragonBoard and a host PC. These are used for serial debugging and ADB connectivity, respectively.
A serial log can be seen on a CuteCom graphical serial terminal or any other serial console.
An ADB log can be seen on the terminal by using the command ‘$adb shell’ followed by ‘#logcat’.
Jumper Parameter Setting
J3 VCCIO0 Set at VCCVAR (the voltage on Bank 0, where IR Tx and Rx parts are connected).
J5 VCCIO1 Set at 1V8. This is the voltage on Bank 1 where the DragonBoard interfaces are wired. Must be set to 1V8 for compatibility with DragonBoard levels.
J19 PWRSEL Set at DGN. Indicates the source of power, will be 2.85V from the DragonBoard’s J6 connector for DragonBoard-related demos. This renders VCCVAR at 2.85V throughout the board.
J14 VCCIO2 Set at VCCVAR so that LEDs can light as required.
J7 VCCIO3 Set at 1.8V. No connections for current demos, set it at the lowest voltage.

Interrupt Configuration1. Identify the GPIO Number
The DragonBoard makes use of ACCIL_IRQ (Pin6) on the J6 connector for interrupt.
As per the schematics (8060DragonBoard_Schematic_CPU_Carrier_Board_(110311).pdf and 8060DragonBoard_Schematic_Main_Board_(091611).pdf), the GPIO-57 pin of APQ8060 is connected to the ACCEL_IRQ pin.
2. Print the IRQ Number
The interrupt number is printed by adding the following lines to the board support package file found in the fol-lowing path:
..../8060_v3/kernel/arch/arm/mach-msm/board-msm8x60.c#define GPIO_IRDETECT_IRQ 57
5
iCEdragon Demo Board
Under ‘static void __init msm8x60_dragon_init(void)’ add the following lines:
uint32_t irq;gpio_request(GPIO_IRDETECT_IRQ, "IR-DETECT"); // REQUEST GPIO 57gpio_export(GPIO_IRDETECT_IRQ, 0); // EXPORT GPIO 57gpio_direction_input(GPIO_IRDETECT_IRQ); // INPUT DIRECTION GPIO 57 printk(KERN_EMERG " PRINTING IRQ NUMBER \n"); // DEBUGirq = gpio_to_irq(GPIO_IRDETECT_IRQ); // GET IRQ NUMBERprintk(KERN_EMERG " IRQ NUMBER of GPIO-57 : %d\n", irq); // DEBUG
Build the kernel and flash boot.img file onto the DragonBoard as explained in Steps 5 and 7.
The boot log generated during reboot will print the IRQ number as follows:
IRQ NUMBER of GPIO-57 : 313
Note: Modified ‘board-msm8x60.c’ is given with this document and can be found in the following location:
/8060_v3/kernel/arch/arm/mach-msm/board-msm8x60.c
3. Identify I2C Device Lines
The I2C device line registered on the J6 connector is identified from the device file of the DragonBoard:
…./8060_v3/kernel/arch/arm/mach-msm/device-msm8x60.c
It is identified that i2c-5 lines are used on the J6 connector (sensor connector). This device lines are used to read and write from the iCEdragon Demo Board.
4. Interrupt Handling Driver in Kernel
The interrupt handling driver file ‘I2C_irdetect_dev.c’ and respective modified ‘Makefile’ are provided with this document. These files exists in the path below:
/8060_v3/kernel/drivers/i2c/
Simply copy the above driver file and Makefile to the following Android kernel path:
…./8060_v3/kernel/drivers/i2c/
Now, proceed to build the kernel as described in the following steps.
5. Build the 8060_V3 Android Kernel for the DragonBoard
a. To clean all the previously-built directories and image files, use the command below:$mke clean
b. To build the kernel source code, use these commands:$sudo -s$cd …./8060_v3/$./build.sh
6
iCEdragon Demo Board
6. Edit init.rc and Rebuild Kernel
When building the kernel source code for first time after using the ‘$make clean’ command, the default init.rc file will be created in this location:
…./8060_v3/out/target/product/msm8660_surf/root
Note: A modified init.rc file is provided with this document and can be found in the following path:
/8060_v3/out/target/product/msm8660_surf/root/init.rc
Use the commands below to edit the init.rc file:
$cd …./8060_v3/out/target/product/msm8660_surf/root$sudo vi init.rc
Add the following lines to the init.rc file:
mount debugfs debugfs /sys/kernel/debugchmod 0777 /dev/i2c-5 chmod 0777 /sys/kernel/debug/IR_detectchmod 0777 /system/etc/dbus.confchown system system /system/etc/dbus.confchown system system /dev/i2c-5chown system system /sys/kernel/debug/IR_detect
After editing the init.rc file, save it and rebuild the kernel for the changes to take effect in the boot.img file.
Re-build the kernel source code using the commands below:
$sudo -s$cd …./8060_v3/$./build.sh
Note: Do not use the ‘$make clean’ command during re-build as this will overwrite to default init.rc file.
Once the build is complete, follow the steps below to flash the boot image to the board.
7. Flash the Boot Image to the DragonBoard
a. Run the command below on the terminal to enter Root Mode:$sudo -s
b. Reboot the DragonBoard in Fastboot Mode. To do this, hold down button 5 on the keypad during reboot.
The DragonBoard can be rebooted to Fastboot Mode by pressing the Power button on the board for few seconds until the power-off option is shown on the touch screen. Now hold down button 5 on key-pad and click the Power Off option shown on the touch screen. Hold down button 5 until the reboot is complete.
Note: Not holding down button 5 on the keypad during reboot will reboot the board with the existing Android operating system.
c. Verify FastBoot Mode. When the board is in FastBoot Mode mode, the screen is blank. Executing the command below on the terminal with root permission will list the FastBoot device number and its name:
$fastboot devices
The board is now ready to be flashed with the boot.img file.

11. Debugging and Troubleshooting in the Kernel and Application
To debug board support files using printk statements, use printk functions with the KERN_EMERG flag.
Example: Printk(KERN_EMERG "MY PRINT LOG\n");
The printk lines can be shown on a serial console.
To enable the Android Debug Log, add the following line in the Android.mk file of your jni directory:
LOCAL_LDLIBS := -llo
Inside JNI ‘C’ code use android_log_print lines in the following format to debug:
#include<android/log.h> #define LOG_TAG "nativeIrdetect"
Example:
__android_log_print(ANDROID_LOG_DEBUG, LOG_TAG,"PRINT LOG \n");__android_log_print(ANDROID_LOG_INFO, "PRINT VALUE=", "%d\n", value);
The debug lines can be observed on a serial console by using the ‘#logcat’ command.
If the android application does not respond, follow the steps below in the correct sequence:
a. Power off the iCEdragon Demo Board by toggling the switch (sw1) to the OFF position.b. Close the IR_scanner application process running in the background.
Android menu > Settings > Applications > Manage Applications > IR_Scanner > Force Stop
c. Power-on the board by toggling the switch (sw1) to the ON position.d. Open the IR_Scanner application from the Android menu and the application is ready to detect any
key press.
Installing the DragonBoard USB Driver in Windows XP1. Download and install the Android Software Development Kit (SDK).2. Start the SDK Manager GUI and install the Google USB Driver package mentioned in the Extras subheading.3. Copy [Android SDK Root]\extras\google\usb_driver to [Android SDK Root]\msm8655-mdp_usb_driver. If there
is no such folder, create a new folder.4. Open the android_winusb.inf (inside of the newly-created directory) file in Notepad or another non-format
appending text editor. Clear the contents of the[Google.NTx86] and [Google.NTamd64] paragraphs so that they contain only the following:
